/*! * \file * \brief User-configurable settings * * Miscellaneous switches: * * A number of macros affect a variety of minor aspects of ICU. * Most of them used to be defined elsewhere (e.g., in utypes.h or platform.h) * and moved here to make them easier to find. * * Switches for excluding parts of ICU library code modules: * * Changing these macros allows building partial, smaller libraries for special purposes. * By default, all modules are built. * The switches are fairly coarse, controlling large modules. * Basic services cannot be turned off. * * Building with any of these options does not guarantee that the * ICU build process will completely work. It is recommended that * the ICU libraries and data be built using the normal build. * At that time you should remove the data used by those services. * After building the ICU data library, you should rebuild the ICU * libraries with these switches customized to your needs. * * @stable ICU 2.4
